Jason Fung - Intermittent Fasting for Type 2 Diabetes Reversal | The Diabetes Code Clinic (Part 2)
Dr. Jason Fung explains that type 2 diabetes is an overflow problem where the body has too much glucose. He emphasizes that carbohydrates are essentially sugars, and reducing their intake can help manage diabetes. By focusing on low carbohydrate diets, individuals can decrease their blood glucose levels. Dr. Fung highlights that proteins and fats do not raise blood glucose levels, unlike carbohydrates. He provides practical dietary advice, suggesting the consumption of green and non-starchy vegetables, proteins like meats and shellfish, and natural fats such as butter and olive oil. He advises avoiding added sugars, starchy carbohydrates, and processed foods. Dr. Fung cites Dr. David Unwin's study, which showed that a low carbohydrate diet could put type 2 diabetes into remission in 46% of patients and normalize pre-diabetes in 93% of cases.
Key Points:
- Type 2 diabetes is caused by excess glucose; reducing carbohydrate intake can help manage it.
- Proteins and fats do not raise blood glucose levels, unlike carbohydrates.
- Low carbohydrate diets can put type 2 diabetes into remission in 46% of cases.
- Avoid added sugars, starchy carbohydrates, and processed foods to manage blood glucose.
- Consume green vegetables, proteins, and natural fats for a balanced diet.
Details:
1. 🎬 Introduction to Low-Carb Diet for Diabetes
- The focus is on achieving the remission of type 2 diabetes through dietary changes, specifically by reversing the condition.
- Low carbohydrate diets are highlighted as an effective strategy for managing type 2 diabetes, which is described as a condition of excess glucose overflow.
- The introduction explains how reducing carbohydrate intake can help control blood sugar levels and potentially lead to diabetes remission.
2. 🍬 Understanding Sugar Overflow in the Body
- The body is likened to a rain barrel where glucose acts as the water; when there's an excess, it spills over, causing health issues such as insulin resistance and type 2 diabetes.
- Excess glucose primarily originates from dietary sources, making dietary control a crucial factor in preventing overflow.
- Low carbohydrate diets are emphasized as a straightforward and effective strategy to manage and reduce glucose levels, preventing the spillover effect.
- Examples of health issues from glucose overflow include increased risk of cardiovascular diseases and nerve damage, underscoring the importance of managing sugar intake.
3. 🥩 Macronutrients: Proteins, Fats, and Carbs
- Proteins are vital for health due to their amino acids, which the body can't produce; a lack of protein can lead to illness.
- Fats are necessary for health, providing essential fatty acids like Omega-3s; a zero fat diet can cause health issues.
- Carbohydrates, such as those found in bread and rice, are not essential as there are no necessary carbohydrates for the body.
4. 🔍 Carbohydrates and Blood Sugar Impact
- Starch, composed of long chains of glucose, is broken down into glucose in the body, raising blood sugar levels significantly.
- Rapidly digested starches, such as those found in processed flour, cause immediate increases in blood glucose levels, similar to pure glucose.
- A study from 1984 demonstrated that consuming 50 grams of glucose causes a significant rise in blood glucose, highlighting the impact of carbohydrates on blood sugar.
- Carbohydrates provide energy but lack essential nutrients like vitamins and minerals, which can be obtained from other foods.
- Proteins and fats, in contrast, do not raise blood glucose levels, making them suitable alternatives for managing type 2 diabetes.
- For those with high blood sugar, such as individuals with type 2 diabetes, focusing on high-protein and high-fat foods instead of carbohydrates can help manage blood sugar levels effectively.

6. 🚫 Foods to Avoid for Diabetes Management
- Avoid added sugars as they raise blood glucose levels significantly. Instead, opt for natural sweeteners like stevia in moderation.
- Eliminate sugary drinks such as sodas, iced teas, fruit juices, and sweetened coffee, as they contribute to high blood sugar. Choose water, herbal teas, or unsweetened beverages.
- Limit intake of starchy carbohydrates like white bread, white potatoes, and white rice; they are refined and quickly convert to glucose. Opt for whole grains like quinoa or barley.
- Be cautious with fat-free foods; they often contain added sugars to compensate for taste, which can elevate blood sugar levels. Check labels for hidden sugars.
- Steer clear of snacks containing processed carbohydrates, such as biscuits, cookies, and crackers, which are high in sugars. Choose nuts or seeds as healthier alternatives.
- Consume fruits in moderation, opting for lower sugar options like berries, apples, and pears. Avoid higher sugar fruits like bananas and mangoes.
- A bowl of rice can equate to approximately 10.1 teaspoons of sugar when converted, whereas broccoli equates to 0.2 teaspoons, illustrating the sugar content difference.
- Understand that carbohydrates are chemically glucose, and excessive intake contributes to high blood glucose levels. Monitor portion sizes and total carb intake.
- For diabetes remission, reduce carbohydrate intake to prevent glucose overflow in the bloodstream. Focus on a balanced diet with lean proteins and healthy fats.
